Apple currently holds around 95.5 percent of the worldwide tablet market,
according to research firm Strategy Analytics, but faces a rising tide of
competition from the likes of the Samsung Galaxy Tab and Research In Motion's
PlayBook. Whether the newest reports about the iPad turn out to be true (if the
rumors surrounding the first iPad proved anything, it's that any "news"
preceding Apple's actual unveiling should be taken with a dump truck worth of
salt), Apple may do well to consider integrating the following features into
its next-generation tablet-if only to blunt the impact of rival devices poised
to flood the marketplace:

Dual Cameras
The first iPad lacked camera modules, a detail its competitors immediately
seized upon to differentiate their own upcoming products. With other tablet PCs
emphasizing their video-conferencing ability (along with Apple itself, via
FaceTime for the iPhone 4 and latest-generation iPod Touch), Steve Jobs and
company will almost certainly feel compelled to give the next-generation iPad
front- and rear-facing cameras of its very own.
Thinner and Lighter

Apple digs thin and light: the newest MacBook Air, for instance, along with
the ever-slimmer iPhone and iPods. The trend is thoroughly baked into Apple's
design language, and its engineers are likely examining how to winnow the form factor
without sacrificing its performance or the quality of the materials. To do so,
Apple may have to develop a new manufacturing process, which Jobs will
doubtlessly "tout" as magical at whatever future unveiling event.
Multiple USB Ports
Soon after the first iPad's release, some users complained about the lack of
USB slots. Again, Apple's competitors
incorporated that feature into their own tablets as a differentiator. While
Apple may publicly tout the simplicity and ease of porting documents via the
iPad's 3G and/or WiFi connection, it could also consider incorporating a pair
of USB ports.
Retina Display
Apple has promoted the ultra-sharp Retina Display as a vital feature of the
iPhone 4 and latest-generation iPod Touch. Retina Display features pixels some
78 micrometers wide, or 326 per inch, in order to make images and text look
continuous. If Apple's engineers can figure out a working method, the Retina
Display could very well find its way into the next version of the iPad-or if
not into this version, a subsequent one.
Three-Axis Gyroscope Sensor
If Apple integrates a three-axis gyroscope sensor into the next-generation
iPad-similar to the one already present in the iPhone 4-it could increase the
device's appeal to developers and consumers as an apps and gaming platform.
